Description

Die Erfindung bezieht sich auf einen Batteriehalter für Flachbaugruppen für eine Batterie oder für einen aufladbaren Akku mit zwei in einer Leiterplatte eingesetzten und verlöteten Kontaktelementen.The invention relates to a battery holder for printed circuit boards for a battery or for a rechargeable battery with two contact elements inserted and soldered in a circuit board.

Elektronische Schalteinrichtungen oder Datenverarbeitungsanlagen weisen eine Vielzahl von Flachbaugruppen auf. Die Flachbaugruppen sind sehr häufig mit Halbleiterspeichem bestückt, u.a. mit sogenannten RAM. Zur Erhaltung der in einem RAM gespeicherten Daten bei fehlender Gesamtstromversorgung, wie sie beispielsweise bei Stromausfall oder bei gezogener Flachbaugruppe der Fall ist, muß eine Stromquelle für die Speisung der RAM-Bausteine vorgesehen sein. Damit die Batterien oder Akkus bei langen Lagerzeiten der Flachbaugruppen nicht schon entleert oder sogar bei Bum-In-Tests frühzeitig beschädigt werden, wurden bisher die Batterien in die Flachbaugruppen sehr häufig erst zum geeigneten Zeitpunkt von Hand eingelötet. Dies ist jedoch umständlich und oft recht lästig. Außerdem läßt sich dann nicht ohne weiteres eine verbrauchte Batterie oder ein untauglich gewordener Akku austauschen.Electronic switching devices or data processing systems have a large number of printed circuit boards. The printed circuit boards are very often equipped with semiconductor memories, e.g. with so-called RAM. To maintain the data stored in a RAM in the absence of a total power supply, such as is the case, for example, in the event of a power failure or when the printed circuit board is removed, a power source must be provided for supplying the RAM modules. So that the batteries or rechargeable batteries are not already emptied during long storage times of the printed circuit boards or even damaged early in bum-in tests, the batteries have so far only been soldered into the printed circuit boards by hand at the appropriate time. However, this is cumbersome and often quite annoying. In addition, a used battery or a battery that has become unsuitable cannot be easily replaced.

Aufgabe der Erfindung ist es daher, einen Batteriehalter für Flachbaugruppen zu schaffen, der ein einfaches Einsetzen und Austauschen der Batterie von Hand ermöglicht. Dabei soll der Austausch auch bei gesteckter Flachbaugruppe möglich sein, damit das RAM dabei von der Gesamtstromversorgung versorgt werden kann. Diese Aufgabe wird erfindungsgemäß mit den kennzeichnenden Merkmalen des Anspruchs 1 gelöstThe object of the invention is therefore to provide a battery holder for printed circuit boards which enables easy insertion and replacement of the battery by hand. The exchange should also be possible when the printed circuit board is plugged in, so that the RAM can be supplied by the total power supply. This object is achieved with the characterizing features of claim 1

Der BatteriehaJter ist vorzugsweise für zylindrische oder ovale Batterien zu verwenden. Er besteht aus den beiden Kontaktelementen, die in vorteilhafter Weise direkt in die Leiterplatte eingesetzt und beim Maschinenlöten der übrigen Bauteile mitgelötet werden. Das erste Kontaktelement ist im wesentlichen aus einem rechtwinklig geformten Blechstück gebildet, das eine parallel zur Leiterplatte angeordnete Auflagefläche und eine senkrecht dazu angeformte Kontaktfläche aufweist. Die Kontaktfläche weist zumindest einen Kontaktpunkt und an den beiden Außenseiten je einen angeformten Lötkontakt auf, der durch die Leiterplatte gesteckt und dort verlötet ist. Die flache Auflagefläche reicht bis in die Nähe des zweiten Kontaktelements und besitzt dort einen weiteren Lötkontakt, der ebenfalls durch die Leiterplatte gesteckt und verlötet ist. Dadurch wird in vorteilhafter Weise eine hohe Stabilität und Kippsicherheit erreicht. Auf der Batterieseite, also zum zweiten Kontaktelement hinweisend, ist auf der Kontaktfläche zumindest ein Kontaktpunkt, beispielsweise in Form einer Warze, angebracht. Das zweite Kontaktelement ist aus einem mehrfach abgewinkelten Blechstück gebildet, das zwei senkrecht zur Leiterplatte angeordnete flächige Schenkel aufweist Diese sind mit einem im rechten Winkel dazu angeformten Joch verbunden. Ferner ist an einem Schenkel rechtwinklig eine Stützfläche angeformt, die zumindest im Bereich der Leiterplatte bis in die Nähe des ersten Kontaktelements reicht und dort einen angeformten Lötkontakt aufweist, der durch die Leiterplatte gesteckt und verlötet ist. An jedem Schenkel ist ebenfalls ein durch die Leiterplatte gesteckter Lötkontakt angeformtThe battery holder should preferably be used for cylindrical or oval batteries. It consists of the two contact elements, which are advantageously inserted directly into the circuit board and are also soldered during machine soldering of the other components. The first contact element is essentially formed from a rectangularly shaped piece of sheet metal, which has a support surface arranged parallel to the printed circuit board and a contact surface integrally formed thereon. The contact surface has at least one contact point and a molded solder contact on each of the two outer sides, which is inserted through the printed circuit board and soldered there. The flat contact surface extends into the vicinity of the second contact element and has an additional solder contact there, which is also inserted and soldered through the circuit board. As a result, high stability and tipping safety are advantageously achieved. On the battery side, ie pointing towards the second contact element, at least one contact point, for example in the form of a wart, is attached to the contact surface. The second contact element is formed from a multi-angled piece of sheet metal which has two flat legs arranged perpendicular to the circuit board. These are connected to a yoke formed at a right angle thereto. Furthermore, a support surface is formed at right angles on one leg, which extends at least in the region of the printed circuit board to the vicinity of the first contact element and has an integrally formed solder contact there, which is inserted and soldered through the printed circuit board. A solder contact inserted through the circuit board is also formed on each leg

Ferner ist am Joch nahezu rechtwinklig zwischen den beiden Schenkeln ein federnder Lappen angeformt, der eine Blattfeder bildet und einen Kontaktpunkt aufweist Die Kontaktierung der Batterie erfolgt an zwei Anlagestellen. Beispielsweise liegt der Pluspol an der Warze der Kontaktfläche des ersten Kontaktelements, der Minuspol an der federnden Kontaktstelle des angeformten, federnden Lappens. Die dadurch erreichte Kontaktkraft ist mit beispielsweise 12 N relativ groß gewählt, um die Oxydschichten oder Verunreinigungen der Metallflächen zu durchstoßen. Die drei Lötanschlüsse des zweiten Kontaktelements gewähren ebenfalls eine hohe Stabilität und Kippsicherheit. Mit der neuerungsgemäßen Ausbildung der beiden Kontaktelemente wird erreicht, daß die Reaktionskräfte nicht unmittelbar auf die Lötpunkte wirken. Dazu kann in vorteilhafter Weise der durch die Leiterplatte gesteckte dritte Lötkontakt des ersten Kontaktelements zusätzlich abgewinkelt sein.Furthermore, a resilient tab is formed on the yoke almost at right angles between the two legs, which forms a leaf spring and has a contact point. The battery is contacted at two contact points. For example, the positive pole lies on the wart of the contact surface of the first contact element, the negative pole on the resilient contact point of the molded, resilient tab. The contact force achieved thereby is chosen to be relatively large, for example 12 N, in order to penetrate the oxide layers or contaminations of the metal surfaces. The three solder connections of the second contact element also ensure high stability and tilt resistance. With the new design of the two contact elements, it is achieved that the reaction forces do not act directly on the soldering points. For this purpose, the third solder contact of the first contact element inserted through the printed circuit board can advantageously be additionally angled.

Anhand der Zeichnung wird die Erfindung näher erläutert Dabei zeigtThe invention is explained in more detail with reference to the drawing

Fig.1 einen erfindungsgemäßen Batteriehalter in perspektivischer Darstellung und1 shows a battery holder according to the invention in perspective and Fig.2 eine Seitenansicht des Batteriehafters.2 shows a side view of the battery holder.

Auf der Leiterplatte 2 einer Flachbaugruppe ist der Batteriehatter in unmittelbarer Nähe der Leiterplattenvorderkante 2a angeordnet. Das hat den Vorteil, daß die Batterie 1 auch bei gesteckter Flachbaugruppe ausgewechselt werden kann. Der Batteriehalter besteht aus zwei Kontaktelementen 3 und 4. Das erste Kontaktelement 3 ist mit seiner senkrecht zur Leiterplatte 2 angeordneten Kontaktfläche 3b mit Hilfe der beiden an den Außenkanten angeformten Lötkontakten 3d in der Leiterplatte 2 eingesteckt und dort verlötet. Die an der Kontaktfläche 3b angeformte Auflagefläche 3a verläuft parallel zur Leiterplatte 2 und weist an ihrer Vorderkante, in der Nähe des zweiten Kontaktelements 4, einen angeformten Lötkontakt 3e auf, der durch die Leiterpiatte gesteckt und auf der gegenüberliegenden Seite abgewinkelt und dort verlötet ist. Die Kontaktfläche 3b des ersten Kontaktelements 3 weist in diesem Ausführungsbeispiel zwei warzenförmige Kontaktpunkte 3c auf, die eine sichere Kontaktgabe mit der Batterie 1 gewährleisten. Das zweite Kontaktelement 4 ist entsprechend der Größe der Batterie 1 gegenüber dem ersten Kontaktelement 3 angeordnet Das Kontaktelement 4 weist zwei senkrecht zur Leiterplatte 2 angeordnete Schenkel 4a auf, die an der Leiterplatte 2 je einen angeformten Lötkontakt 4f besitzen, der durch die Leiterplatte 2 gesteckt und verlötet ist. Er kann auf der gegenüberliegenden Seite . auch abgewinkelt sein. Mit dem im rechten Winkel zu einem Schenkel 4a des Kontaktelements 4 angeformten Stützblech 4c wird ein dritter Auflage- und Lötanschlußpunkt erzielt. Das Stützblech 4c ist stufenförmig ausgebildet und reicht im Bereich der Leiterplatte 2 sehr nahe an das Kontaktelement 3 heran. Dort ist der Lötkontakt 4g angeformt, der durch die Leiterplatte 2 gesteckt und dort verlötet ist. Auch dieser Lötanschluß 4g kann auf der anderen Seite der Leiterplatte 2 abgewinkelt werden. Zur Erhöhung der Stabilität ist bei diesem Ausführungsbeispiel in der Nähe des Schenkels 4a an der Stützfläche 4c ein zusätzlicher Lötanschluß 4h angeformt Die beiden Schenkel 4a sind mit einem im rechten Winkel zu den Schenkeln 4a angeordneten Joch 4b verbunden. An das Joch 4b ist zwischen den beiden Schenkeln 4a im rechten Winkel ein Lappen 4e angeformt, der wie eine Blattfeder wirkt und an seinem freien Ende einen Kontaktpunkt 4e besitzt. Dieser Kontaktpunkt ist in Form eines spitz zulaufenden Lappens ausgebildet der senkrecht zur Blattfeder angeformt ist und zur Batterie hinweistThe battery charger is arranged on the printed circuit board 2 of a printed circuit board in the immediate vicinity of the leading edge 2a of the printed circuit board. This has the advantage that the battery 1 can also be replaced when the printed circuit board is inserted. The battery holder consists of two contact elements 3 and 4. The first contact element 3, with its contact surface 3b arranged perpendicular to the printed circuit board 2, is inserted into the printed circuit board 2 with the aid of the two solder contacts 3d formed on the outer edges and is soldered there. The support surface 3a formed on the contact surface 3b runs parallel to the printed circuit board 2 and has on its front edge, in the vicinity of the second contact element 4, a molded solder contact 3e which is inserted through the printed circuit board and angled on the opposite side and soldered there. In this exemplary embodiment, the contact surface 3b of the first contact element 3 has two wart-shaped contact points 3c, which ensure reliable contact with the battery 1. The second contact element 4 is arranged according to the size of the battery 1 with respect to the first contact element 3. The contact element 4 has two legs 4a arranged perpendicular to the printed circuit board 2, each of which has a molded solder contact 4f on the printed circuit board 2, which is inserted through the printed circuit board 2 and is soldered. It can be on the opposite side. also be angled. With the support plate 4c formed at right angles to a leg 4a of the contact element 4, a third support and soldering connection point is achieved. The support plate 4c is stepped and extends very close to the contact element 3 in the area of the printed circuit board 2. The soldering contact 4g is formed there, which is inserted through the printed circuit board 2 and soldered there. This solder connection 4g can also be angled on the other side of the circuit board 2. To increase the stability, an additional solder connection 4h is formed on the support surface 4c in the vicinity of the leg 4a. The two legs 4a are connected to a yoke 4b arranged at right angles to the legs 4a. A flap 4e is formed on the yoke 4b between the two legs 4a at a right angle, which acts like a leaf spring and has a contact point 4e at its free end. This contact point is designed in the form of a tapered flap which is formed perpendicular to the leaf spring and points towards the battery

Die Anordnung und Ausbildung der beiden Kontaktelemente 3 und 4 ist so gewählt, daß insbesondere bei eingestecktem Nickel-Cadmium-Akkus 1 eine Lage des Akkus erreicht wird, die die gefalzte Dichtungsstelle 1 nach oben zeigen läßt. Dadurch wird bei undichten Akkus das Auslaufen verhindert, so daß keine Beschädigung der Flachbaugruppe auftreten kann. Um die relativ hohen Toleranzen der Batteriehöhen von beispielsweise 1.5 mm ausgleichen zu können, ist ein möglichst großer Federweg des Kontaktpunkts 4e mit der erfindungsgemäßen Batteriehalterung bezweckt worden. Dies wurde dadurch erreicht, daß die Blattfeder 4e im Bereich des Jochs 4b zwischen den beiden Schenkeln 4a hineinragt. Schon bei einer kleinen Bewegung des Jochs 4b wird die Blattfeder 4d im Verhältnis c zu b ausgelenkt Zusätzlich wird dabei der Federweg der Blattfeder 4d ausgenützt. Dies ist in der Fig.2 gestrichelt angedeutetThe arrangement and design of the two contact elements 3 and 4 is selected so that, particularly when the nickel-cadmium accumulator 1 is inserted, a position of the accumulator is achieved which allows the folded sealing point 1 to point upwards. This prevents leakage in the case of leaking batteries, so that no damage to the printed circuit board can occur. In order to be able to compensate for the relatively high tolerances of the battery heights of, for example, 1.5 mm, the greatest possible spring travel of the contact point 4e with the battery holder according to the invention was intended. This was achieved in that the leaf spring 4e protrudes in the area of the yoke 4b between the two legs 4a. Even with a small movement of the yoke 4b, the leaf spring 4d is deflected in the ratio c to b. In addition, the spring travel of the leaf spring 4d is used. This is indicated by dashed lines in FIG
